Abstract
Identity document processing equipment with a mechanism designed to maintain tension in a ribbon used in a processing operation in the processing equipment. The tension maintaining mechanism is separate from the supply roll and the take-up roll for the ribbon, eliminating the need for clutches or brakes attached to the supply or take-up rolls to achieve tensioning. Since the tension maintaining mechanism is separate from the supply roll and the take-up roll, the inertia of the supply roll or the take-up roll does not affect the tension on the ribbon during use of the processing equipment.
